Virtualbox Additions fail after install

[BrianMMcClain]

The following SSH command responded with a non-zero exit status.
Vagrant assumes that this means the command failed!

mount -t vboxsf -o uid=`id -u vagrant`,gid=`id -g vagrant` /vagrant /vagrant

This is because the kernel is rebuilt but not the guest additions. This is fixed with:

sudo /etc/init.d/vboxadd setup

Find a way to detect and do this automatically

Nise BOSH's bin/init script installs the linux-image-virtual package to enable cgroups and quota. So we need always need to reinstall vbox additions.
